Do Linux users pay a "Microsoft tax?"

"I think he's right -- if you want Linux and have to buy a
Windows-based PC on which to install it, you're paying a Microsoft
tax. That tax, though, isn't nearly as costly as the Apple tax.

"How much is the tax? To know that, you need to know how much
Microsoft charges PC makers for Windows, and neither Microsoft nor
the PC makers are talking. However, the number is most likely
between $60 and $100 on desktops and laptops, according to what
I've been able to find out. The figure for netbooks is likely far
lower."
